What Has Changed in the Colorado Interconnection Queue

2026-06-11 → 2026-09-07 · every difference we have observed, not just this week's

We have recorded 37 changes across 34 projects in the Colorado queue since 2026-06-11: 2 new entries, 29 status changes, 3 in-service dates moved (3 of them later), 0 capacity revisions and 3 projects no longer listed.

Counted across 38 comparisons between consecutive sealed snapshots, 39 snapshots from 2026-06-11 to 2026-09-07 (between 1 and 7 days apart). One change is one difference observed for one project between two consecutive snapshots, so a project that moved in three different weeks is counted three times: these 37 changes come from 34 distinct projects.

This is the part that cannot be refetched. Every ISO publishes its current queue for free and then overwrites it. None of them keep an archive. The dates in the left-hand column below exist only because we sealed a copy that week, and after the fact nobody can reconstruct them, including us.

Where our coverage starts and stops. These are limits of the archive, not events in the market.

SPP enters our archive on 2026-08-14 with 1,022 projects. That is our collection starting, not projects entering the queue, so none of those rows is counted as an arrival here. We have no earlier copy to have seen them absent from.
SPP is not observed from 2026-08-13 onward; we last read it on 2026-08-12, when it carried 1,020 projects. Those rows are excluded rather than counted as departures. A queue we did not fetch has not emptied.

A project that disappears from a report is recorded here as no longer listed, not as withdrawn. ISOs drop rows for several reasons and only some of them mean the project died. We publish the observation, not a cause we cannot see.

The ISOs publish today's queue and overwrite it, so no archive exists. We keep a weekly copy. Leave your email and we'll send you each week's changes in Colorado, from new entries to projects that came off the list.

In-service dates that moved

The date a project told its ISO it would start commercial operation, against what the same project published at the previous snapshot. A date appearing for the first time is not counted here, because there is no earlier plan for it to have moved from.

Where each number came from

Read this before quoting a figure. We re-read every source every week, but a weekly read of an unchanged file is not weekly data. These have not moved in a while: SPP last changed 2026-09-05 (3 identical reads since). Those rows are exactly as current as the ISO's own published file, and no more.

This week's changes · How this is collected

Compiled from each ISO's own published interconnection queue report. Queue position is not a permit, a contract, or a guarantee that a project will be built; most projects in every queue are eventually withdrawn. Figures are reproduced as published, are provided for informational purposes only, and carry no warranty of accuracy or completeness. Always verify against the ISO's own report before relying on any figure.
